摘要
背景:前牵引治疗能有效改变儿童骨性Ⅲ类错牙合患者的颅颌面结构关系,同时也改变了颞下颌关节结构。但是关于前牵引颞下颌关节改变和颅颌面变化的相关性,尚无确切研究结果。目的:分析儿童骨性Ⅲ类错牙合患者前牵引矫治前后牙颌面改变与颞下颌关节改变的相关性,探讨前牵引矫治对儿童颞下颌关节的影响。方法:上颌前方牵引矫治儿童骨性Ⅲ类错牙合29例,男16例,女13例,年龄8-11岁,对前牵引矫治前后牙颌面和颞下颌关节的改变进行头影测量分析、坐标系统定位测量分析,数据分析采用配对t检验和Mann-Whitney检验及Pearson相关性分析。结果与结论:前牵引治疗前后骨骼矢状方向发生明显改变,颞下颌关节窝和髁状突在X轴改变明显,在Y轴改变不明显,颞下颌关节后间隙明显减小;相关性分析发现,颞下颌关节与牙颌面结构改变之间存在中等相关关系。结果表明,前牵引矫治后,牙颌面与颞下颌关节结构均有明显改变,且颞下颌关节骨改建与牙颌面改变之间存在中等相关关系,但没有密切相关关系。
BACKGROUND:Maxillary protraction treatment can effectively change the craniofacial structural relationship and the temporomandibular joint structure of children with skeletal Class Ⅲ malocclusion.However,there are no definitive findings regarding the correlation between changes in the temporomandibular joint and craniomaxillofacial changes after maxillary protraction.OBJECTIVE:To analyze the correlation between dentofacial changes and temporomandibular joint changes in children with skeletal class Ⅲ malocclusion before and after maxillary protraction and to investigate the effect of maxillary protraction on the tempo romandibular joint of children.METHODS:A total of 29 children with s keletal class Ⅲ malocclusion,including 16 boys and 13 girls,aged 8-11 years,were treated by maxillary protraction.The changes of dentofacial and temporomandibular joint were subjected to cephalometric analysis and coordinate system positioning measurement.Paired t-test,Mann-Whitnev test and Pearson correlation analysis were conducted.RESULTS AND CONCLUSION:The sagittal relationship of the jaw changed obviously before and after maxillary protraction.The glenoid fossa and condyle changed significantly in the X axis but not in the Y axis.The posterior space of the temporomandibular joint was significantly reduced.Correlation analysis revealed a moderate correlation between the temporomandibular joint and dentofacial structural changes.To conclude,after maxillary protraction,both dentofacial and temporomandibular joint structures have significant changes,and there is a moderate correlation between tempo romandibular joint remodeling and dentofacial changes,but no close correlation exists between them.
